Hmm, I don't know bjam very well, so I may be missing something here.
I'd guess the time is spent mostly for constructing the dependency
graph. I didn't mean to suggest that bjam has to be invoked multiple
times. I'm sure bjam has its own idea of a 'task' / 'rule' or however it
is called. All that would be needed is a definition of a task that
invokes qmtest for a particular test, which then is invoked whenever
bjam decides that its time to run it again.

Anyways, my whole point is to show that even though qmtest itself
doesn't manage dependencies, it's easy enough to hook it up with
tools that are designed to do just that.
